When I came back home after four years, I expected familiar faces, old memories, and my father's endless lectures. I didn't expect Bangchan . My dad's best friend. 34 years old. Cold eyes. Tailored black suits. A man who spoke only when necessary and never smiled unless he had a reason. He'd watched me grow up, but now...he looked at me differently. Not warmly. Not affectionately. Cautiously. Like I was the one thing he couldn't afford to lose control over. Every Sunday, he'd come over for dinner, sitting across the table from me, pretending not to notice the way my eyes lingered on him. "Stop staring," he muttered one night. "Then stop giving me reasons to," I whispered back. His jaw clenched. "You're playing a dangerous game." "Who said I wanted to play safe?" He stood abruptly, leaving the room before my father noticed anything. After that, he avoided me. Ignored my calls. Left every room I entered. Until one stormy evening when my father asked him to drive me home. The silence inside the car was suffocating. Rain hammered against the windshield. "You're making this difficult," Bangchan finally said. "You're the one running." "Because I know where this ends." "Do you?" He pulled the car over, gripping the steering wheel so tightly his knuckles turned white. "You're my best friend's daughter," he said, his voice low. "And that should be enough for me to walk away." "But it isn't." His eyes met mine for the first time that night, filled with conflict, restraint, and secrets he'd buried for years. "No," he admitted quietly. "It isn't." Outside, the rain refused to stop. Inside the car, neither of us moved. Some boundaries weren't crossed in a single moment. They were erased one heartbeat at a time. And the darkest stories always begin with the words no one should ever say: This stays between us.
